James Ralph Bailey, known professionally as J.R. Bailey, was an American R&B singer and songwriter born on June 17, 1937, in Baltimore, Maryland. He was a prominent figure in the music industry, particularly noted for his contributions to the doo-wop and R&B genres. Bailey was a member of several vocal groups, including The Halos, The Cadillacs, and The Crickets (not to be confused with Buddy Holly's Crickets), before embarking on a solo career.

As a solo artist, he released music under the name Jimmy Bailey on Columbia Records starting in 1965. He was not only a performer but also an accomplished songwriter. Bailey co-wrote several hit songs, including "Everybody Plays the Fool" by The Main Ingredient and "Sweet Music, Soft Lights and You" by Isaac Hayes & Millie Jackson. His song "Love, Love, Love," released in 1972, was later covered by Donny Hathaway. Bailey's songwriting collaborations often included work with Ken Williams and Vernon Harrell, leading to hits like "Soul Shing-A-Ling" and "Seven Days Too Long" by Chuck Wood.

In addition to his solo work, Bailey was a sought-after background vocalist for notable artists such as Aretha Franklin, Roberta Flack, Donny Hathaway, Melvin Van Peebles, and Jimmy Castor. His influence extended into the modern era when Alicia Keys sampled his song "Let Me Prove My Love to You" for her 2003 single "You Don't Know My Name."

J.R. Bailey passed away on September 6, 1985, leaving behind a legacy of influential music that continues to resonate within the R&B genre.
